Production of Renewable Aromatic Compounds by Catalytic Fast Pyrolysis of Lignocellulosic Biomass with Bifunctional Ga/ZSM-5 Catalysts...

摘要

Catalytic fast pyrolysis (CFP) is a promising technology for the direct production of renewable aromatic compounds, including benzene, toluene, and xylenes (BTX) from solid biomass. In this single-step process, biomass-including wood, agricultural wastes, and fast-growing energy crops-is fed into a fluidized-bed reactor where the biomass first thermally decomposes to form pyrolysis vapors. These vapors then enter the zeolite catalysts, which are also inside the fluidized-bed reactor, and are converted into the desired aromatic compounds and olefins along with CO, CO , HO, and coke.
